rIhe invention relates to signals for use on automobiles to indicatewhen and in which direction a turn is to be made. Y

One aim of the invention isfto provide a casing having an elongatedlight-pervious portion and two pointed light-pervious portions at theends of saidelongated portion, providing a double-ended arrow, and toprovide for simuitaneously illuminating said elongated portion andeither one of said pointed portions, thereby forming an illuminatedarrow pointingin either direction in which a turn is to be made.

Another object is to provide a novel and advantageous casing structurein which various separate parts are held assembled in a unique way andmay readily be disassembled to such an extent as to give access Vto theilluminating bulbs for the light-pervious portions, whenever replacementbecomes necressary. i i@ A still further aim is to make novel provisionfor illuminating the aforesaid elongated light-pervious portion tosubstantially a uniform extent throughout its length, with only thenecessity of one bulb.

With the foregoing in view, theY invention resides in the novel subjectmatter hereinafter described and claimed, description being accomplishedby reference to the accompanying dra-wing Fig. 1 is a perspective viewof the complete turning signal.

Fig. 2 is a horizontal sectional view on line 2-2 of Fig. 1.

Figs. 3 and 4 are transverse sectional views on lines 3 3 and 4 4respectively of Fig. 2.

Fig. 5 is a fragmentary vertical sectional view on line 5-5 of Fig. 2.

Fig. 6 is a disassembled perspective view partly broken away.

A preferred construction `has been illustrated and will Vbe ratherspecifically described, with the understanding khowever that Within thescope ofthe invention as claimed, variations may be made.

The numeral 10 on the drawings denotes a horizontally elongated maincasing section having an elongated light-pervious portion 11 ofCelluloid or the like, extending throughout itslength, said portion 11being preferably of some distinct color such as red.

-Mounted at the ends ofthe casing section 1 0 arel two pointed casingsections 12 having light-perviousportions 13 of Celluloid or the like,said portions 13 being the same color as the portion 11 and co-actingwith the latter in forming a double-endedV arrow. A bulb -14 isprovidedV for illuminating the lightpervious portion 11, andtwo bulbs 15are providedfor illuminating the portions 13 respectively. It' will thusbe seen that by simultaneously illuminating the bulb 14 and either ofthe bulbs 15, an illuminated arrow will be displayed pointing in thedirection in which a turn is to be made. For effecting illumination ofthe bulbs, any desired switch (not shown) vmay be employed, locatedwithin convenient reach ofthe driver or perhaps operated by mechanicalinstead of manual means. Y' Y y A horizontallyelongated plate 16 forms.the front wall or'the casing section 10, the

upper and lower edge portions of Vsaid wall being folded'upon themselvestov provide upper and lower. longitudinal guideways 17 and 18, the upperfolded edge being formed with openings 19 to receive bolts or the `likefor attaching the-entire structure to a machine. The top ywall 20,bottom wall 21 and rear wall 22 of the casing section 10 are preferablyformed from one piece of sheet metal bent-into substantially channelshape and having upper and lower flanges 23 and 24 at its freelongitudinal edges, said flanges being slidably engaged with theguideways 17 and 18 respectively. This slidable engagement or" thegreater part of the casing section 10,-with the plate 16, allows theformer to be slid upon the latter to give access to the bulb 14 whennecessary. v

. Atrthe juncture of the wall 22 with the walls-` and 21, the metal ofthe casing section l() is bent to provide flanged guideways 25 withwhich the light-pervious portion 11 tudinally spaced perforations 26.Prefer-- ably, the perforations near the bulb 14 are small and thosedistant from said bulb are largei, and the perforations between saidsmall and large perforations gradually increase in size from said smalltoward said large 'perforations The rays 'of -light from the bulb 14lmay be reflected toward the light-pervious Yportion 11 if desired, byan appropriate reflector 27 disposed longitudinally in the jcasingsection 10, said reflector having oblique'ends 28 :eirtending to theends of the perforated Wall 22.

The pointed casing sections 12 'abut the ends of the section 1() andattheir inner sides, said sections 12 are each provided with two parallellaterally Iprojecting flanges 29 and 30. These flanges overlap the endsVof the plate 16 and the ends 'of the wall 22 respectively. Each casingsection 12 is also provided with an upstanding flange 31 and with adownwardly projecting flange 32, these flanges of 4the two casingsections 12 being slidably engaged with tlie'ends of the vguideways 17and 1S respectively. Therear side of each casing section 12 is formed bythe liglit-pervious portion 18 and a -fra1ne33 therefor, ythe latterlbeing flanged at 34 for detacliableengagement with the flange 35,-sothat the rear of tlie'casing may be jdetached when desired to giveaccess to the bulb 15. The frame 33 overlaps ythe flange 30, and thethree 4parts 29, 30 and 33 are formed with openings 36, 37 and 88respectively which aline with an opening 39 in the .plate V16 and withan opening 40 in the wall 22 and strip 11. The ends 28 of the reflector27 are formed with vnotchesorother openings 41 in aliiieinent with thevaforesaid openings, and athrough-bolt 32 passes vthrough fall of theopenings as shown in Fig. 2, said bolt preferably having a sleeve-nut 43Ain the opening 39. lThe structure is the saine at each end of thesignal and it will be seen that Vthe three easing sections are normallyheld in rigidly assembled vrelation with the plate 16. Upon removal ofveither vbolt 42 however, either casing section 12 may be removed,thereby allowing sliding of the casing section 10 upon the plate 16 togive access to the bulb 14. Also, removal of either bolt 42 allowsremoval of the rear wall of either casing 12, for access to the bulb 15.

It will be seen from the Yforegoing that the invention is of rathersimple and inexpensive construction, yet that it will be ein cient anddesirable. Vhen ay turn is to be made in one direction,the-light-.perviousportion 11 and one of the portions 13 are jointlyilluminated, thereby displaying an illuininated arrow pointing in saiddirection.

vWhen a turn is to be made in the other direction, the other of saidportions 13 is illuminated simultaneously with the portion 11, therebyformingan illuminated arrow pointing in the other direction.

lVhile the various details disclosed may be considered as preferred,attention is again invited to the fact that within the scope of theinvention as claimed, variations may be made.
